SETTING AXLETREES.

Specification of Letters Patent No. 29,132, dated July 17, 1860.

T o all whom it may concern:

Be it known that we, JOHN N. ARVIN and SAMUEL H. PERKINS, of Valparaiso, in the county of Porter and State of Indiana, have invented a new and useful Machine for Setting Axletrees for Wagons and other Vehicles; and we do hereby declare that the following is a full, clear, and exact descrip tion of the construction and operation of the same, reference being had to the annexed drawings, and letters of reference marked thereon, making a part of this specification.

Figure l, is a perspective view of the whole machine, in which f, represents the bench; A, A, the rests; C, C, the sets, and Z the set screws with cranks. Fig. 2, represents the sections marked C, C, in Fig. 1, to be further described, and Fig. 3 represents profile views of Fig. 2, marked C, and profile views of sections A, A, Fig. l.

Referring to Fig. l, the bench f, is made of a squared piece of timber 6 feet long, and 4L inches thick and 6 inches wide, set upon legs of proper height, and irmness. The rests A, A, Fig. l, and A, Fig. 2, are made of cast iron 6 inches high, 3 inches wide and inch thick with ears extending upward about 2 inches, to receive the set screws el. The rests are fastened to the bench by inch iron bolts, and can be moved or graduated so as to rest immediately under the shoulders of the axletree to be set. The sets C, C, are of cast iron, and are fastened to the bench in the same manner as the rests, and are composed of two parts, the standards D in Figs. 2 and 3, which are 4 inches high to wide and L inch thick, and are pierced byv the set screws d.

Directions for use-Place a straight edge on the rests A, A, extending through the rings B, B, lower the set screws d as much below thestraight edge as you wish to give pitch to the axle, set the lateral set screws, d by the assistance of the straight edge a suiicient distance back, to give the desired gather; heat the axletree at the shoulders, place it on the rests A, A, the ends extending through the rigs B, B, then fasten the axletree at A, A, with the set screws cl, d, then t-urn the set screws d, d, in the rings B, B, until the points of the axel come in contact with the set screws d and d.

Vhat we claim as our invention and desire to secure by Letters Patent, is-

An improved mode of setting axletrees, and giving them the required pitch and gather by means of metallic set screws, rests, and sets, or their equivalents, as exhibited, and described by the specifications herewith.
